Slick 4 Migrate execution layer to Cats Effect 3 and FS2: replace Future-based thread pool with CE3 blocking dispatcher, db.run() now returns F[R], db.stream() returns Stream[F, T], transactions roll back on fiber cancellation. Remove AsyncExecutor, ExecutionContext from DBIOAction combinators and model-building API. Add savepoint primitives. Drop Scala 2.12 support. See doc/paradox/migrating-to-slick4.md for the full migration guide.
